Voskoboynikova N. Increasing the Ecological Safety of Heat-and-cool-supply Systems of Buildings by means of Energy Redistribution between Alternative and Traditional Sources

Dissertation is devoted to the study of ecological safety of heat-and-cool-supply systems of buildings, the development of scientific methods of complex assessment of environmental impact and creating the mechanism for increasing ecological safety through sustainable use of alternative and traditional energy sources. The researcher worked out the method of complex evaluating the ecological safety of these systems based on the index and expressed through grounded indicators considering versatile environmental impact aspects and intensity of different types of technogenic influence on a human. The mathematical model and algorithm of increasing the ecological safety of heat-and-cool-supplying were created. This model is based on redistribution of wind and solar energy between hot-water-supplying, heating, cooling and water treatment with a maximum level of substitution of traditional resources by renewables. The ecological safety indices for different types of systems in climatic conditions of Southern region were simulated mathematically. The optimization task of heat-and-cool-supplying on the example of particular residential building was solved. The opportunity of improving the ecological safety of existing in Mykolaiv region systems by equipping them with wind and solar plants was assessed.
